78This Part of this Schedule applies to claims for capital allowances, that is, allowances under the [1990 c. 1.] Capital Allowances Act 1990 or provisions to which the Tax Acts apply as if they were contained in that Act.
79(1)A claim for capital allowances must be made by being included in the claimant company’s company tax return for the accounting period for which the claim is made.
(2)It may be included in the return originally made or by amendment.
80A claim for capital allowances must specify the amount claimed, which must be an amount which is quantified at the time the claim is made.
81A claim for capital allowances may be amended or withdrawn by the claimant company only by amending its company tax return.
82(1)A claim for capital allowances may be made, amended or withdrawn at any time up to whichever is the last of the following dates—
(a)the first anniversary of the filing date for the company tax return of the claimant company for the accounting period for which the claim is made;
(b)if notice of enquiry is given into that return, 30 days after the enquiry is completed;
(c)if after such an enquiry the Inland Revenue amend the return under paragraph 34(2), 30 days after notice of the amendment is issued;
(d)if an appeal is brought against such an amendment, 30 days after the date on which the appeal is finally determined.
(2)A claim for capital allowances may be made, amended or withdrawn at a later time if the Inland Revenue allow it.
(3)The time limits otherwise applicable to amendment of a company tax return do not apply to an amendment to the extent that it makes, amends or withdraws a claim for capital allowances within the time allowed by or under this paragraph.
(4)The references in sub-paragraph (1) to an enquiry into a company tax return do not include an enquiry restricted to a previous amendment making, amending or withdrawing a claim for capital allowances.
An enquiry is so restricted if—
(a)the scope of the enquiry is limited as mentioned in paragraph 25(2), and
(b)the amendment giving rise to the enquiry consisted of the making, amending or withdrawing of a claim for capital allowances.
83(1)This paragraph applies if the effect of a claim for capital allowances is to reduce the amount available by way of capital allowances for another accounting period of the company for which a company tax return has been delivered.
(2)The company has 30 days within which to make any necessary amendments of the company tax return for that other period.
(3)If it does not do so, the Inland Revenue may by notice in writing to the company amend the return to make it consistent with the amount available by way of capital allowances.
(4)The time limits otherwise applicable to amendment of a company tax return do not prevent an amendment being made under sub-paragraph (2) or (3).
(5)An appeal may be brought by the company against any such amendment.
(6)Notice of appeal must be given—
(a)in writing,
(b)within 30 days after notice of the amendment was issued,
(c)to the officer of the Board by whom the notice of amendment was issued.
